PUMPING APPARATUS.

Application filed October 23, 1,923.

To all whom 'it may concern.'

Be it known that I, CLARnNon WARNER, a citizen of the United States of America, residing at Dayton, county of Montgomery,

l State of Ohio, have invented certain new and useful Improvements 1n Pumping Appara-tus, of which the following is a full, clear, and exact description.

'T his invention relates to pumping apparatus of the suction type, and has for its object the provision of a simple and compact pumping unit, tending toward a reduction in the number of parts.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of o-ne forni of the present invention is clearly shown.

In the drawings:

Fig. 1 is a view partly in elevation and partly in section of a pumping apparatus comprising the present invention.

- Fig. 2 is a sec-tional view on a reduced yscale taken on the line 2-2 of Fig. 1.

In the drawings, a power head frame 20 supports an electric motor 21 and encloses power driven mechanism which may be of the type disclosed in the copending application of G. A. Buvinger and C. Warner, Serial No. 626,174, filed March 19, 1923 (DL 147 An aperture 22is provided in end Wall 23 of frame 20. A cross head guide 24, supported within frame 20 receives across head 25 which is attached to a connecting rod 26 by a pin 27, the rod 26 being connected with the power driven mechanism referred to, whereby the cross head 25 is reciprocated within the cross head guide 24. Cross head 25 is provided with a threaded extension 28.

A pump frame 30 is provided with an eX- tension 31 being threaded adjacent the end thereof, and of such size as to be received by the opening 22 in wall 23 of frame 20. EX- tension 31 receives a nut 32 which when drawn up on extension 31 tightens the joint between wall 23 of frame 2O and wall 33 of ump frame 30. Frame 30 is provided with inlet chamber 35 having a vbaille 36 for keeping the pump valves under water to prevent drying out, and also for keeping the pump primed, and an outlet chamber 37 having a baille 38 for maintaining a column of water in the pump and also keep-ing the valves Serial No. 670,356.

under water. Removable plugs 39 and 40 are provided in frame 30 for priming of the outlet and inlet chambers 37 and 35frespectively when the pump is first installed. IVall 41 of inlet chamber 35 is provided with an opening 42 for receiving a` removable plug 43 for a purpose to be described, and chamber is adapted to be drained through means of a plug 43. Pipe connects inlet chamber 35 with a suitablesource of supply, and pipe 46 lconnects the outlet chamber 37 with suitable service pipes. `@utlet chamber 37 is adapted 'to be drained through means of a removable plug 46. Inlet and outlet chambers 35 and 37 respectively are connected by a cylindrical aperture 50 in alignment with aperture 42 in wall 41 between walls 51 and 52'c1 of pump frame 30, and a cylinder 52 is press-fitted between these two walls, and is internally threaded adjacentthe end thereof nearest the inlet chamber 35, for receiving a removable valve seat 53 having po-rts 54 and 55 which connect the cylinder 52 with the inlet chamber 35. A screw 56 is mounted in valve seat 53 and provides a support for a spring 57 which bears against disc valve 58 slidably mounted ou said screw, for normally resiliently maintaining valve` 58 on its seat 53, thereby controlling ports 54 and 55.

Tall 33 and extension 31 of pump frame 30 are provided with an aperture 60 in alignment with apertures 42 and 50. Aperture 60 permits reciprocation.therethrough of a connecting rod or plunger 65, one end of which has connection with the threaded` portion 28 of cross head 25, the other end extending into cylinder 52 and having threaded connection with a piston 74, comprising a valve cage 66 and a plug 75 having threaded connection with the valve cage 66. Connecting rod is of such size as to displace substantially one half of the volume of water which the cylinderV 52 is capable of holding during the operation of the pump. Plug is provided with an opening 67 connecting cylinder 52 with the interior of cage 66, and cage 66 is provided with outlet ports 68 and 69 leading into the interior of cylinder 52. An annular groove 77a in plug 75 receives packing 78 which is held in place between plug 75 and valve cage 66 when plug 75 is screwed into cage 66. Plug 75 provides a piston head and also a seat 75a for a valve 72 to be described. A

screw T0; is provided with a reduced portion 76 which slidably fits within a bore Tl in inwardly extending boss 7l which is toi-meidY integrally with the valve cage 66, the head o't screw 70 extending into the opening 6T in plug 75. disc valve 72 is mounted on the threaded portion 77 oi' screw T0 and is securely held` thereon between a washer 72 which engages the head of screw 70 and a washer; 72b having threaded connection with portion 'TT ot' screw 70. A springY 79 which surrounds boss 7l. bears against washer 72 and the wall S() of valve cage G6 `to normally resiliently maintain the valve '72 on its seat 75.

Aperture 60k is recessed providing;` a seat 85 forpacking 86 which is spaced 'trom packing 87 by a. packing gland 8S. A. packing, nut 89 has threaded connection with the inner wallsurface of extension 3l and when tightened up tends to hold'packing' 86. packing` gland 88 and packing` ST in position tor sealing the aperture 60 through which the connecting rod or plunger G5 is adapted to be reciprocated. Rod 65 is provided with wrench holes 90 and 91 for a purpose to be described.

Mode of operation.

Then the rod 65 is moved to the right thereby moving piston 74 to the rightl as viewed Vin Fig. l, by the pump driving.; mechanism referred to.) a vacuum will be created inthe cylinder 52 whereby the valve 58 Will be opened and water will be drawn trom the source off supply through pipe 45. inlet chamber 35' up over battle 3f, through ports 54tand 55 into the interior oitf cylinder 52. Then when the piston le is moved to the left, as viewed in Fig. l, the valve will be closed and valve 72 will be openefh thereby permittingv water to flow from the interior of' cylinder 52 through inlet openingo? and through outlet openings 68 and 69-into the outlet chamber 3T. up over battle plate 38 and down into outlet pipe t6 to the service pipes. However, inasmuch as the rodfor plunger is of such size as to displaeesubstantially one halt of the water which the cylinder 52 is capable of holding' during operation or" the pump, about one halt of thevw'ater in cylinder 52 will he discharged into the outlet chamber on the stroke of the piston 74 to the lett4 as viewed in Fig. l. Then upon the return stroke ot piston V74 to the' right, the water remaining' in' cylinder 52 will be 'forced into the outlet chamber, `up over the baille 38 and down into outlet pipe 4G. rlhus there is a vdischarge of water for each stroke of the piston 74 in either direction, thus constitutingthe pump" a double acting discharge pump. It' should be noted, however, that the pump has a single acting intake as de- ,scribedV This result is accompiished by a A'trom the extension then the nut 32 is loosened and slipped back on the rod G5. Then the inlet pipe l5 and outlet pipo to should be disconnected from the pump trame 230, and a wrench ennagei'l in the holes 90 and 91 in rod (S5 to thereby loosen the rod 65 from the threaded portion 28 ot" cross head The pump trame ll() with the rod 65 piston 711-, cylinder 52 and valves .3S :md 'i2 may then be removed in assembled relu` tion trom the power head trame 2th the cx,- tensiou 3l and rod 65 being: withdrawn through opening 22 in, wall 23 of frame 20.

The rod G5 may be removed through openinpT 42 in the pump trame 30 by removing' plug;` 43 and loosening vulve seat 53 from the cylinder 52. Removal ot valve seats 53 brings valve 58 with it in assembled relation. Piston 'T4 including head 75, valvi` enge (Sti and valve T2 may be removed :is a unit from the rod G5. Piston head 75may then be removed from valve cage 66, and valve 72, including' spring' T9, screw 70 and washers 72" and 72h may be lifted trom valve 'aac (36 in assembled relation.

(ilpeninpg l2 in wall del ot'Y trame il() is ol' sullicient size to permit insertion or withdrawal ot the cylinder 52.
